Polymer-Based Materials of Controlled Permeability and Application of Photoinduced Magnetism

摘要

Substantial technical progress was achieved during the reporting period in the following project areas: (A) increased organic-based materials options for materials with high permeability near room temperature (RT); (B) successfully initiated a program to prepare RT organic-based magnets that remain air stable to significantly above RT; (C) elucidated novel means for photonic control of magnetism through incorporation of photosensitive azo groups in the organic moiety; (D) Elucidated origins of magnetism and conductivity in RT organic-based magnet V(TCNE)x; (E) Demonstrated the ability of organic semiconductors to transport spin in giant magnetoresistance (GMR) and tunneling magnetoresistance (TMR) device structures using rubrene as a model organic semiconductor; (F) demonstrated the ability of V(TCNE)x to inject spin into organic semiconductors such as rubrene, demonstrating the potential for all organic, flexible, air stable, light weight spintronics, as well as hybrid spintronics.
